We are finishing up the matching AC•15 MKII Upgrade Power Supply for our PEQ•MKII Phono Preamp.

It uses a 35VA encapsulated toroid transformer, has AC line filtering, 120~240V input selection, dual 15VAC outputs with dual common-mode choke output filtering. This can als be used to power PLC•1 for 120~240V operation but offers no sonic benefits.Being that PLC•1 is a purely passive signal path, the power supply is only used for control circuits.Looks are the same as VDC but no LED and uses a 7 pin DIN connector for output. Hope to ship around May 1st.Cost will be $299
